IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 142,136, dated August 26, 1873; application filed July 12, 1873.

To all whom it may concern:

ythe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings making part of this specilication, in which- I Figure 1, Plate l, is an elevation of the moldboard side of the improved plow. Fig. 2, Plate l, is a top view of the beam and a section through the left-hand handle, showing the truss-braces and clevis. Figs. 3, 4, 5, and, Plate 1, are views in detail of several parts of the plow. Fig. 7, Plate 1 is a bottom view of the plow. Fig. 8, Plate 2, is a side view, partly in section, with the mold-board removed.

Similar letters of reference indicate corresponding parts in the several gures.

My invention relates to single mold-board plows; and has for its obj ect bracing, strengthening, and stiffening all parts of a plow in a more substantial manner than hitherto, whereby a light, and vat the same time a very strong, plow is obtained, as will be `hereinafter explained.

The following description of my invention will enable others skilled in the art to understand it.

In the accompanying drawings, A represents a -metallic beam, which is curved behind so as to form also the standard for the plow. B represents the mold-board. C represents the plow point and share, and D Dl represent the handles of the plow. The mold-board and the share, with its point, are secured to the lower curved end of the standard portion of the beam A by means of a bolt, 10which is passed through said standard and through the land-side portion of the share and point. I further secure the share to the standard by means of a broad angular plate,fm, which is bolted to the inside of the standard by a single bolt, which also passes through the land-side bar C', and by bolts which pass through the share and mold-board. This angular plate m not only serves as a means for connecting the land-side, the share, and the lower part of the mold-board to the standard, but it also affords .upper end of the brace g3 is bentat g2, through which the bolt passes that secures the moldboard to it. The lower part of this brace has a lip or foot, g4, formed on one side of it, which extends beneath the lowerextremity of the beam-handle D', and aiords a firm support therefor. A plate, g, is secured rigidly to the handle D, the lower end of` which abuts.

against the upper edge of the brace g3. This 'plateprotects the handle from wear, and affords a smooth surface for the earth to slide over. The mold-board is also secured to the two handles D Dl by means of a diagonal spreader, g1, which also forms a brace. This spreader and brace g1 is bent, as represented in Figs. 7 and 8, and its ends are firmly bolted to the lower ends of the two handles D D', while at an intermediate point between its ends it is secured by a bolt, o, to the lmoldboard, and affords ,a support for this moldboard. The beam A is braced, strengthened, and secured to the beam-handle D by the following means: The clevis consists of two pieces, which are pivoted at their ends to the beam A by means of atransverse bolt, tonwhich is also connected the front ends of two rods, c c. These rods c c extend backward and outward,`and are connected by a bolt, j, to the extremities of tubes d1 d1, which are formed on the sides of two clamps, d d. The clamps d d are flanged at d2 and shaped to [it snugly the bend at the junction of the standard with the beam A, and by means of bolts 'i these two clamps are iirmly secured on opposite sides of the beam, as clearly shown in the drawings. To the bolt j is also secured the front ends of two braces or ties, 7c k, which extend parallel backward, and

v'are secured at their rear extremities to the ends of tubes which are formed on two clasps, a a, that embrace the handle D. The clasps It will be seen thit the rods c c, with the braces 7c L, form ties between the beam A and beam-handle, and also that these rods truss the beam against lateral strain, andenable 'me to use a Very light beam, and at the same males rods k k are attached, substantially as dcscribed.

3. The flanged clamps d d, constructed with tubes Il d1, and confined at the bend of the beam A by means of a bolt, j, to which the rear ends of the truss-rods c c are connected, substantially as described.

4. The brace g3, bent at g2 and g4, and connected to the mold-board, the standard, and the beam-handle, substantially as described.

5. The spreader-brace g1, connected to the handle D D and having bolted to it the moldboard D, substantially as described.
